What a new tax client costs, from ads to referrals

July is when tax practice owners finally have time to ask what last season’s marketing cost and whether it was worth it. The honest answer starts with an awkward fact: none of the big advertising benchmark reports has an accounting or tax preparation category. Anyone who quotes you a precise “cost per tax client” for your market is guessing.

What the published numbers can do is set a range, and the rules around tax marketing explain why the cheapest-looking channel is not always the cheapest.

The nearest benchmarks, and what they leave out

WordStream by LocaliQ’s 2026 Google Ads benchmarks, published in May and covering April 2025 to March 2026 across 13,474 US search campaigns, report two categories a tax practice sits between. Finance & Insurance came in at a median cost per click of $3.39 and a median cost per lead of $74.44, with 2.64% of clicks becoming leads. Business Services ran $5.87 per click and $93.69 per lead, converting 4.85% of clicks. The median across all industries was $66.69 per lead.

Both categories got cheaper per lead than in the 2025 edition, which put Finance & Insurance at $83.93 and Business Services at $103.54 for April 2024 to March 2025.

The ceiling for nearby search terms shows up in an older LocaliQ legal report: Tax Law, meaning tax attorneys, ran $120.30 per lead for April 2022 to March 2023. Searches like “IRS notice help” and “back taxes” sit closer to that end than “tax preparer near me” does.

None of these are tax practices, and all of them are medians. Your cost depends on how many firms bid in your area, how good the landing page is and, above all, when you run the ads.

Season decides the price more than channel does

The IRS’s own weekly filing statistics show how compressed the demand is. Through April 17, 2026, the IRS had received about 140.2 million individual returns. Of those, about 51.8 million, roughly 37%, arrived in the three weeks after March 27. Every preparer in town is bidding in those weeks. By June the same searches come from far fewer people, and far fewer firms are still bidding on them.

That is why one blended cost per lead for the year tells you little. A new filer in early February and an extension filer in late May are different purchases at different prices, and the report should show them separately.

Local Services Ads: cheap leads with no safety net

Local Services Ads charge per lead rather than per click, and for “tax preparer near me” in season they can put the firm at the very top of the page with the Google Verified badge. The tax version is the barest Google runs. Its help pages state that tax specialists get phone leads only, with no message leads, call recordings, direct booking or lead credits. A wrong number, a sales call or a caller looking for free filing is a paid lead with no way to dispute it, and there is no recording in the ad account to check what happened.

That does not rule the channel out. It means the real cost per client depends on who answers the phone. Invoca’s 2025 benchmark report, built on more than 60 million calls, found financial services calls converting at 29% and business services calls at 22%. Invoca’s customers are mostly large contact centers, so a small office will see its own number, but the point holds: a missed call in March is the most expensive lead the firm buys all year.

Search ads: more control, more work

Google search campaigns cost more per lead in the benchmarks and give you the things Local Services Ads take away. You write the words, which matters when Circular 230 and your state board set rules on what a tax ad may claim. You choose the searches, which lets business returns, bookkeeping and IRS notices each get their own campaign and landing page. And you can exclude the free-filing and job-seeker searches that drain a tax budget in January.

Search is also the only paid channel here that reaches the business owner in July looking for a new bookkeeper, when Local Services Ads have little to offer.

Referrals and returning clients: no media cost, and a rule

Returning filers and referrals are the cheapest clients a practice has, and they are why lead cost should be judged against years of work rather than one return. The IRS figures show how much of the market runs through professionals at all: through May 8, 2026, about 75.3 million of the 141.0 million e-filed individual returns came from tax professionals.

The catch is in the federal rules on tax return information. A preparer may use its client list to send tax information and to offer more tax return preparation. Offering bookkeeping, payroll or advisory services to that list, or uploading it to an ad platform, needs the client’s consent through the process those rules describe. The firms that get this right put a consent step into the engagement letter or onboarding, so the follow-up is lawful before it is written.

Referrals also get checked. BrightLocal’s 2026 consumer survey found 97% of consumers read reviews for local businesses and 47% would not use a business with fewer than 20, so a referred client who finds eight reviews from 2023 may never call.

What the monthly work is worth

The comparison changes again once a client moves from a yearly return to monthly work. In the 2024 CPA.com and AICPA PCPS benchmark survey, reported by the Journal of Accountancy, practices with a formal written plan for client accounting and advisory services reported $27,761 in median average annual client revenue, and only 10% of respondents still billed hourly as their main method. Firms with more than half their revenue from industry niches reported 38% higher median revenue from that work.

A cost per lead that looks high for one individual return can look very different against a monthly bookkeeping client, and a niche gives a search or social campaign something specific to say. Construction, professional services, not-for-profits and retail were the most common niches in that survey.

What we are telling clients

• Report the season in two halves: January to April 15, then April 16 to October 15, each with its own cost per signed client.
• Keep Local Services Ads for the weeks someone can answer every call live, and track those calls yourself.
• Give business returns, IRS notices and bookkeeping their own search campaigns and pages rather than one “tax services” ad.
• Add a consent step to onboarding before any bookkeeping or payroll offer goes to tax-only clients.
• Ask every client for a review after delivery, so a referral finds recent ones when it checks you.
• Plan a summer bookkeeping offer for one niche while the staff has time to onboard monthly clients.

The cheapest channel on paper is rarely the cheapest per signed client once the season, the phone and the rules are counted. Our page for accountants and tax preparers sets out how we would order the work, and our review requests cover the part that decides whether a referral calls.
